Electroplating is the process of plating, or coating, an article with a thin layer of metal by using a liquid solution of the metal and an electric current that causes the metal to deposit on the article's surface. Some objects that are electroplated are automobile bumpers, grills, and trim; metal furniture; aircraft parts; electronic components; small appliances; and plumbing fixtures. Electroplating provides a protective surface and helps an object resist wear, corrosion, or abrasion. The various workers who carry out this process are known as electroplaters or platers. There are approximately 35,640 metal and plastic plating and coating machine setters, operators, and tenders employed in the United States.
